Convinced the [Megatherium] sent to Royal College of Physicians [by Woodbine Parish] belongs to same formation as bones he sent home.

He misses society. "I often conjecture what will become of me; my wishes certainly would make me a country clergyman. – You expect sadly more than I shall ever do in Nat. Hist: I am only a sort of Jackall, a lions provider; but I wish I was sure there were lions enough."
